To all-iiwuhom it may concern.'

Be it known that I, JAMES OMAR OAKLEY,

a subject of theKing of Great Britain,and

residing at the city of Montreal, in the Province of Quebec, in the Dominionof Canada, have inventedv a new and useful Car Door, of which the following is' the specification.

The invention relates to a car door as described in the present specification and illustrated in the accompanying drawingia' that form partof the saine. -f

The invention consists essentially of the novel features of construction pointed out broadly and 'specifically in the claims for novelty following'a description containing for the' doors vso that they will always be ready foriimniediate use; to avoid waste ofl grain and vreduce the cost of labour in han-- .dling and'gene'ral upkeep; to supply a door that will be easy to operate in closing and opening the doorways of the car; to prevent' the grain from working under the door 30 y grain to coineout in as teadystrea'mwithout any liindrance; andl generally to pro- I vide car doors that-will' be cheap to manufacture, durableun, construction and eiiicient in use. l

' In the drawings, Figurev 1 'isa perspective view showing the Idoor"construction.A 'Figure 2 is a cross sectional view of a car l`body.showing the doors in their closed posiigu're is a crossisectiona'l view of a carl showing'the doorswin their openedposition. Figure 4 is a perspective view` of asection 45l of the door showing the hinge connections of the boards.`

when in its closed position; to allow the l of the lower portion Figure 9 is a perspective detail of a lock-J ing dog fitted to the bracket. Figure 1 0 isa sectional Viewv of a portion of the door showing` the hinge connection.

Like numerals ofJ reference indicate cor'- responding parts in the-various figures.

Referring to the drawings, the car 10 suitable for grain or other cargoes has the door openings in the side'walls surrounded by the frames 11 and `12, said frames having the parallel -door posts.12/on one side 0.5

and' the parallel door posts 14'on" the other.

The tracksfl and 16 on the one side of the car partially close in the vertical recesses in the posts 13 and form guideways Jfor the door and yextend upwardly\.aiid are curved l0 at 17 and 18 and project across the carat v suilicient distance from the ceiling to permit a door to. slide along there on top, said tracks being supportedfroin the ceiling by 7 The other side 'of the car similar tracks 20 and 21 lpartially close similar recesses in the" door posts on that side and extend upwardly and turn in easycurves 22 and'23 r and project across vthe car at a convenient ,30 distance below the tracks l5 and 16 to per' mit" the door on that side to run thereon, said tracks20: and 2 1 are supported by the same hangers v19. v i Tl e door 2 4 is formed of the narrow 85 cross boards 25 in heavy slot forni tonguedA and groov d inte one another and joined by- Aflexible vertical wires 26 spaced one froui' the -other in the width of the door and having eyes27 through which the screws-28 are 9b eyes 29 .at the joints ofthe boards-through which the hinge pins 30 are inserted. a The hinge pins 30 havefdouble offsets 95 -forrning the angle ends 31 and 32 thereby .accounting for the thickness of the boards' in projecting; the said angle 'ends into the. vertical slots ,of the door posts behind the tracks 15 and 16. These anglev ends form,- '100 ing therunning gear of thel door andfslidving up to its place under the cary ceiling.`

The lower end of the door 2 4 is out out f to form 'a slot 33 which is lined by the metal angle bar 34 for convenience'in pry- 105 ing the door to give it a start in the operationof opening.

-Tlie locking dog is -formed with the V-shaped jaw 36 and is pivoted on the door post so as to engage the outer corner of the top board of the door and be locked to that position by sliding it on its pivot into a transverse section of a V-shaped slot 37. The longitudinal section of said slot permitting the loosening of the dog in the operations of opening the door.

, The door is in its upward position held by the dog 38 pivotally securedv to the bracket 39 rigid with the.. door frame and this dog is formed with the projecting iinger 4() and stop 4l and curved on the side 42 below said stop so that on lifting said dog from/behind the door in its upward position where it has been holding it against the stop at the end 'ofthe track the complete door will slide to its closed position and the boards runffreely under this dog.

On .the other side of the car the door` is shown in two sections 43 and 44 which may or may not be used that way and the illustration is merely to explain how readily in this-construction apiece may be added without actually being part cfg-the door and 'this` is particularly useful in cars built to v carry very heavy loads.

i flowmg.

In the operation of this invention the weight of the grainkeeps the. dooi's tightly to their positionagainst the door posts and the angle ends of-.the hinged yrods 'are be-v hind' the tracks and as soon as the caireaches its destination the locking pawl is removed from the top of the door .in-.the

p manner described and the lower. end -of the door is pried upwardly to start the grain This soon 'relieves the weight of the grain-behind the door so that a comparatively light shove will send .the grain door to its position under the ceiling where it locked by the upper dog, then-the .car

can be dumped or unloaded in any way 'without affecting the door whichis well /out -of the wayf and if desirable the car 45 can be iised yfor other purposes for the r'etreadl members a What I claim is:`

turn journey and both4 doors remain to their 'locked position under the ceiling.

A car door comprlsing a plurality of slats longitudinally hinged at the joints and operating as a roll door and 'hinge pins` having double osets atthe ends forming hangers for the door in its sliding and stored positions, trackways secured over vertical recesses in door-posts and therebeyond across the car under thecar door comprising a plurality of l ceiling and suspended therefrom.
